Agriculture and Climate Change (Commonwealth Union) _ Bovine tuberculosis (TB) remains a significant concern for farmers, with rising numbers of reactors detected in recent years, according to data from the Department of Agriculture, Food and the Marine (DAFM). In 2023, 28,868 TB test reactions were recorded in cattle, highlighting the urgent need for effective preventive measures. Here are some strategies farmers can adopt to minimize the spread and breakdown of their herds:
Genetics Management
Implement targeted culling of older animals within herds with a TB history, particularly those previously exposed to infection, to minimize future reactor risks. Employ the economic breeding index (EBI) to select sires with enhanced resistance to bovine TB, thereby reducing breakdown risks, especially in persistently affected herds.
Stock Procurement Practices
To mitigate the introduction of diseases, it’s advisable to minimize the purchase of new animals whenever feasible. Conducting thorough research into the tuberculosis (TB) status and past disease history of herds under consideration is crucial before making any purchases. Additionally, exploring alternatives such as outsourcing the rearing of heifers can help reduce the risk of disease introduction and alleviate the workload on the farm. By implementing these measures, farmers can better safeguard the health and well-being of their herds while minimizing the potential impact of diseases on farm productivity and profitability.
Wildlife Control Measures
To prevent TB transmission, it’s crucial to prevent contact between livestock and wildlife, a common source of the disease. Notify DAFM about badger sets on the farm and restrict livestock access to these areas. Elevate troughs at least 1m off the ground and ensure concentrates storage is wildlife-proof to minimize the risk of TB transmission. These proactive measures can help reduce the likelihood of disease spread and protect the health of the herd.
By implementing these proactive measures, farmers can help mitigate the risk of bovine TB outbreaks and protect the health and productivity of their livestock. Collaboration with relevant authorities and adherence to recommended guidelines are crucial in effectively managing this persistent challenge in the farming community.
